david - ivan was not reporting any bug that could be fixed - he was saying that it is impossible for libreJS to determine if a script is obfuscated or the original source - if the only available version of the script is obfuscated then the GPL does not apply because all requirements are not satisfiable - for this reason, any yet unseen obfuscated script should be considered non-free regardless of it's reported license the only way libreJS can accurately deem a script to be free is either if it is an original non-obfuscated source that matches identically to a previously cataloged copy that has a verified license or an it is an obfuscated script that matches identically to a previously cataloged copy of an obfuscated script which has been previously verified to have been produced from the original source that has a verified license - beyond that, i think the halting problem would need to be solved first just as you do for the FSD, this would require a human to verify the reported license of each and every yet un-cataloged script then either shipping with libreJS checksums for all known scripts on earth as a white-list or having every script that every user downloads sent to a central server for verification which would be as much of a privacy concern as the script itself - also it should be clear from that any such catalog would be incomplete at best, especially at the rate the web changes
